Audit Analysis

The Safe Water Programme in Nigeria has a VVB-confirmed combined additionality test and documented safeguards, but suffers from significant data gaps: no verified emission reductions, a 0% leakage deduction with contradictory justifications across documents, and no buffer pool or permanence mechanism stated. Multiple contradictions between the PDD and validation report undermine confidence in the project's data reliability.

Red Flags

  • Leakage deduction of 0% with justification described as 'not addressed' in the validation report, contradicting the PDD's 'deemed negligible' claim
  • No buffer pool percentage stated and reversal events explicitly 'not addressed' in available documents, leaving permanence risk unquantified
  • No verified emission reduction figure available to validate the 290,960 tCO2e lifetime claim
  • Monitoring period (Jul–Dec 2022) predates the crediting period (Jan 2024–Jan 2029), meaning no in-period performance data exists
  • Corrective action required to update the safeguarding principles assessment, indicating incomplete compliance at validation
